    • The invention relates to thermosetting compositions containing isocyanurate ring(s) prepared through chain extension of an epoxy resin (a) with carboxyl-functional oligomers (b), which are the reaction product of polyols (i) containing one or more isocyanurate ring(s) and polycarboxylic acids or their anhydrides (ii). The polyols (i) containing one or more isocyanurate ring(s) can be prepared from the reactions of tris (2-hydroxyalkyl) isocyanurates with a modifier from a caprolactone or alkylene oxide, or glycidyl ester or glycidyl ether and mixtures thereof. The epoxy-functional thermosetting compositions containing an isocyanurate ring(s) can be further reacted with unsaturated acids, preferably (meth)acrylic acid, to obtain a curable polyacrylate. Both epoxy-functional isocyanurate and acrylate-functional isocyanurate thermosetting compositions can be further modified with a polyisocyanate to produce a composition that is useful as a reactive adhesive, binder or in other applications.
    • 本发明涉及含有通过环氧树脂(a)与羧基官能的低聚物(b)的链延伸制备的异氰脲酸酯环的热固性组合物,其是含有一个或多个异氰脲酸酯环的多元醇(i)的反应产物 )和多元羧酸或其酸酐(ii)。 含有一个或多个异氰脲酸酯环的多元醇(i)可以由三(2-羟烷基)异氰脲酸酯与来自己内酯或烯化氧的改性剂或缩水甘油酯或缩水甘油醚及其混合物的反应制备。 含有异氰脲酸酯环的环氧官能性热固性组合物可以进一步与不饱和酸(优选(甲基)丙烯酸)反应得到可固化的聚丙烯酸酯。 环氧官能的异氰脲酸酯和丙烯酸酯官能的异氰脲酸酯热固性组合物可以用多异氰酸酯进一步改性,以产生可用作反应性粘合剂,粘合剂或其它应用的组合物。

    • Two-part adhesive compositions are described. The two-part adhesives have a first part and a second part, said composition comprising at least one aromatic epoxy resin in the first part; at least one amine curing agent in the second part; and at least one ester in at least one of the first and/or second part. The ester corresponds to the general formula R2—CO—OR1; wherein R1 is an organic moiety comprising at least one of (i) at least one epoxy group or (ii) at least one acryl group and R2 is a branched alkyl group. The structural adhesive may be used to form bonded joints between adherents having clean surfaces, as well as those having surfaces contaminated with hydrocarbon-containing materials, such as oils, processing aids and lubricating agents.
    • 描述两部分粘合剂组合物。 两部分粘合剂具有第一部分和第二部分,所述组合物在第一部分中包含至少一种芳族环氧树脂; 第二部分中的至少一种胺固化剂; 和在第一和/或第二部分中的至少一个中的至少一个酯。 该酯对应于通式R2-CO-OR1; 其中R1是包含(i)至少一个环氧基团或(ii)至少一个丙烯酰基团中的至少一个的有机部分,R 2是支链烷基。 结构粘合剂可以用于在具有干净表面的粘合剂之间形成粘合接头,以及具有被含烃材料(例如油,加工助剂和润滑剂)污染的表面的结合粘合剂。
